Abstract
The invention discloses a valve core of a delay self-closing water faucet. The valve core comprises a valve body, a pressing handwheel and an external adjustment nut, wherein the pressing handwheel and the external adjustment nut are arranged on the valve body; a pressing connecting rod matched with the pressing handwheel is arranged in the valve body; a spring supporting seat sleeved on the pressing connecting rod is arranged in the valve body; a pressing offset spring is arranged between the spring supporting seat and the pressing handwheel; and a delay time adjustment device for guaranteeing the stability of delay time is arranged in the valve body and consists of a water storage cavity, a delay time adjustment seat, a water storage cavity piston arranged in the delay time adjustment seat, a delay time internal adjustment screw matched with the water storage cavity piston and a balance spring sleeved on the water storage cavity piston. The valve core has a delay self-closing function; at high water pressure or low water pressure, the consistency of the delay time can be kept, so that the influence of the water pressure on the valve core is reduced, and the stability of the delay time is improved; and the delay time of closing can be adjusted according to the requirement of a user.
Description
Technical field
The present invention relates to the bath articles field, relate in particular to a kind of delay-self-closing faucet valve core.
Background technique
The delay-self-closing water tap that uses at present adopts fixed groove or aperture to make time-delay water storage cavity intake tunnel technology mostly, and it is downward to press handwheel drive water storage cavity inner carrier; Under hydraulic action, piston and connecting rod hermetic separation have been discharged the water in the chamber fast; After loosing one's grip, act on down piston and connecting rod seal closure simultaneously pushing Returnning spring and piston reset spring; The piston water that moves up is inhaled into water storage cavity from fixed groove or aperture, and water plays damping function, and piston can only slowly move up; Behind the certain hour, throttle down when piston rises to valve body sealing face.Though such water tap can realize prolonging self-closing function; But make time-delay water storage cavity intake tunnel technology owing to adopted fixed groove or aperture; Delay time was long when hydraulic pressure was low; Delay time was too short when delay balance spring hydraulic pressure was high, and delay time is non-adjustable, and it is too short to be difficult to control delay time batch conformity and whole delay time.
Summary of the invention
The present invention is in order to overcome the defective of existing technology, and purpose is to provide a kind of delay-self-closing faucet valve core, and can regulate the length and the weak point of delay time as requested.
The technical solution adopted for the present invention to solve the technical problems is: a kind of delay-self-closing faucet valve core; Comprise that pushing of being provided with on valve body, the valve body is provided with in handwheel, the valve body and pushes the connecting rod of pushing that handwheel cooperates; Be provided with in the described valve body and be placed in the spring support of pushing on the connecting rod, spring support and push to be provided with between the handwheel and push Returnning spring; Be provided with in the described valve body and can protect the whole stable delay adjustment device of delay time, delay adjustment device by water storage cavity, time-delay regulate seat, be located at time-delay regulate a water storage cavity piston in the seat, with time-delay that the water storage cavity piston cooperates in accent screw and the balance spring that is placed on the water storage cavity piston form.
Aforesaid time-delay adjusting seat is for the two-stage cylindrical structural and be provided with the counterbore step and the center via hole, and it is that outside thread is connected with the internal thread of valve body that a front end large cylinder is regulated in time-delay, and is provided with the sealing of O type circle; The rear end small cylinder is provided with the water storage cavity intake tunnel.Third level cylinder plays fixing spring and position-limiting action, and outer rim has seal ring, and integral body is placed on time-delay and regulates on the seat counterbore step, and with transferring screw in the time-delay, forms the water storage cavity intake tunnel.
Aforesaid water storage cavity piston is to place time-delay to regulate three grades of cylindrical bodys on the counterbore step of seat, and it is little that prime cylinder external diameter is regulated seat center via hole than time-delay; Cylinder ratio time-delay adjusting seat center, second level via hole is big and be with the delay balance spring, and the end face of second level cylinder is provided with chamfering.
Transfer screw to be provided with the hydraulic pressure that links to each other with the water storage cavity piston in the aforesaid time-delay and detect the hole.
Aforesaid bottom of pushing connecting rod is connected with piston rod, and the bottom of piston rod is connected with piston, and piston is provided with piston reset spring, is provided with lip-type packing between piston and the valve interior wall.
Aforesaid water storage cavity is complemented each other to form by piston, valve body, time-delay adjusting seat, water storage cavity piston.
Aforesaid valve body is provided with water intake and water outlet, is provided with water-inlet cavity that is communicated with water intake and the water chamber that is communicated with water outlet in the valve body.
Also be provided with guiding in the aforesaid valve body and decide screw and decide the hexagonal spigot nut of screw fit with guiding, the hexagonal spigot nut is connected with piston.
Also be provided with on the aforesaid valve body and be positioned at the outer adjusting nut of pushing the handwheel below.
The aforesaid internal thread connecting end cylindrical of pushing connecting rod adopts inverted cone-shaped structure.
Transferring in the described time-delay has hydraulic pressure to detect the hole on the screw; Link to each other with the water storage cavity piston, but the overall delay time of manual tune is regulated clockwise; Delay time increases; Regulate delay time counterclockwise and reduce, because the reaction force and the water storage cavity piston third level cylinder position-limiting action of balance spring, the water storage cavity intake tunnel remains a fixed gap.When hydraulic pressure was high, balance spring was compressed, and the water storage cavity piston forward moves, and the intake tunnel useful area reduces, and delay time increases; When hydraulic pressure hanged down, balance spring resetted, and the water storage cavity piston moves in the other direction, and the intake tunnel useful area increases, and delay time shortens; Can keep time-delay basicly stable.Outside valve body, the outer nut of regulating is arranged, also can regulate delay time, to regulate clockwise, delay time increases, and regulates counterclockwise, and delay time reduces, and when helping producing in batches, keeps the conformity of delay time.Push connecting rod internal thread connecting end and adopt reversed structure,, improved the stability of delay time to reduce the influence of hydraulic pressure.
In sum, delay-self-closing faucet valve core of the present invention is compared the spool of existing technology, can realize prolonging self-closing function; Delay time is adjustable and stable, is easy to control the conformity of delay time and the stability of whole delay time, no matter when hydraulic pressure height or hydraulic pressure are low; The conformity that can both keep delay time; Reduced the influence of hydraulic pressure, improved the stability of delay time, can also regulate the time of time-delay closing by user's requirement to this spool.
